Understanding VEX IQ Connectors and Standoffs

VEX plastic connectors and standoffs are the fasteners for the VEX plastic construction system. They are available in many colors to provide a customized and creative look for the robot. These connectors/standoffs are provided in the Super Kit and the Foundation Add-on Kit, as well as being available in assorted packs of a specific type. The functions of VEX plastic connectors/standoffs range from general to very specific uses depending on the type of connector. These connectors include:


Pins are used to connect many components on the robot from the Electronics to the Structure of the robot. Pins come in three varieties and nine colors:

  • Connector Pins are designed to be inserted into the holes of components for attachment. There are 1x1 Connector Pins which are designed to connect a single component to another, such as connecting the robot’s brain to a beam. (An example of this can be seen in the VEX IQ Clawbot build instructions.) There are 1x2 Connector pins which connect a single component to two additional components, such as connecting a Corner Connector to a 2X Beam and then attaching an additional 1X Beam. Last, there are 2x2 Connector Pins which can attach two layers of components to two additional layers of components.

  • Capped Connector Pins provide another type connection in designs where there may be a risk of a standard Connector Pin being pulled out because the cap can not be pulled through a hole. Capped Connector Pins can also be used to reinforce an assembly after it has been assembled because the pins can be inserted from the outside surface. These pins are designed to be pushed through the hole in one component and into the hole of the next. There are 0x2 pins for connecting two components together and 0x3 pins for connecting three layers of components.
  • Thin Sheet Connector Pins are used specifically for attaching thick paper, card stock, or thin plastic sheeting to the robot.  Some robotics game rules allow non-functional decorations to be applied upon the robot, these pins are ideal for this application.

Standoffs are used to separate two parts from one another while creating a rigid connection. An example of this would be, separating two 2X Beams so a series of drive gears can be placed between them. Standoffs can also be assembled to handle game pieces, such as making a fork on the end of an arm.  Standoffs are available in 0.5x, 1x, 2x, 4x, and 6x lengths. Standoffs have an End Standoff Connector which can create a pivot point at the end of the standoff. Standoffs also have Mini Standoff Connectors and Standard Standoff Connectors which allows standoffs to be connected to one another.

Corner Connectors

Corner Connectors come in a variety of orientations, allowing for a nearly endless number of options to create three-dimensional designs connecting Beams, Plates and other components. The following connectors are found in the VEX IQ Super Kit:

  • 2X Wide Corner Connectors:
    • Available in 2X2, 1X2, and 2X1 configurations
  • 2X Wide Offset Corner Connectors:
    • Available in 1X2, 2X1, 1X1, configurations
  • Large and Small Chassis Corner Connectors
  • 1X Wide 1x1 Offset Corner Connector:
    • For additional spacing within a corner
  • Double 2x Wide, 2x2 Corner Connectors:
    • Used to separate and connect two parallel components

There are also additional versions of Corner Connectors in the VEX Plastic Add-on Packs, which can be found at the VEX website.
